Scotogenic models are among the most popular possibilities to link dark matter and neutrino masses. In this work we discuss a variant of the Scotogenic model that includes charged fermions and a doublet with hypercharge $3/2$. Neutrino masses are induced at the one-loop level thanks to the states belonging to the dark sector. However, in contrast to the standard Scotogenic model, only the scalar dark matter candidate is viable in this version. After presenting the model and explaining some particularities about neutrino mass generation, we concentrate on its dark matter phenomenology. We show that the observed dark matter relic density can be correctly reproduced in the usual parameter space regions found for the standard Scotogenic model or the Inert Doublet model. In addition, the presence of the charged fermions may open up new regions, provided some tuning of the parameters is allowed.
A modular $A_4$ symmetric Scotogenic model for Neutrino mass and Dark Matter
模对称性在中微子和夸克领域一直是无可挑剔的。因此,我们提出了一种基于模$A_4$对称性的暗生模型,通过辐射机制实现了单圈水平的中微子质量产生。此外,轻子味违反过程$μ\to e γ$和μ子$g-2$异常也得到解决。最轻的马约拉纳费米子被证明是潜在的暗物质候选者,通过适当的分配模块权重而变得稳定。用惰性标量和新的$U(1)$规范玻色子作为媒介的湮灭计算了相同的残余密度。
Scotogenic neutrino mass with large $SU(2)_L$ multiplet fields
我们构造了一个引入大$SU(2)_L$多重态场而不增加额外对称性的暗生中微子质量模型。我们引入了额外的标量场,如七重态,五重态和四重态,其中我们使四重态标量的真空期望值为零,而七重态和五重态发展为非零。然后通过引入五重态费米子在单圈水平上产生中微子质量。我们分析了中微子质量矩阵,考虑到轻子味破坏的约束,并讨论了对撞机物理关于带电费米子从大多重态场。我们分析了五重态费米子的产生和衰变,以及在14 TeV和27 TeV LHC上的发现范围。
